Hi Skyrunner,
I have thought about electrifying my ATF, but for now will be sticking to my gas engine mostly due to the ease of use. There is a guy back east that has been producing electric paramotors for a few years, and his latest design is quite powerful called the SP140 which would have plenty of thrust for a 103 legal trike.
I found this in his FAQs:
“Is just the motor and battery available to buy on its own?
The battery or motor can be bought by themselves to mount to another frame. The motor, ESC, and battery are the highest cost components. In order to make electric paramotors affordable we worked hard on making the frame low cost to manufacture. Where as other gas paramotor frames will cost around $2000 we make ours for around $500 So ordering everything but the frame will not save the typical high cost expense of the frame.
Also the Sp140 is purpose built to allowed batteries to be easily swapped and make a seamless experience.”
